The Landing on Long Island in the Territory of New Guinea was part of the Huon Peninsula campaign, a series of operations that made up Operation Cartwheel, General Douglas MacArthur's campaign to encircle the major Japanese base at Rabaul. Located at the northern end of the Vitiaz Strait, Long Island was an important staging point for Japanese barges moving between Rabaul and Wewak until 26 December 1943, when a force of 220 Australian and American soldiers landed on the island. It was not occupied by the Japanese at the time, and there was no fighting. At the time, it represented the furthest Allied advance into Japanese-held territory. It was developed into a radar station.
